mbira

The Array mbira /əmˈbɪərə/ is a handcrafted modern musical instrument with a unique harp- or bell-like sound. It is made in the United States by its inventor Bill Wesley and manufactured by Wesley with Patrick Hadley in San Diego, California, United States. Its development began in the 1960s.[1] It is a radical redesign of the Shona African mbira from Zimbabwe and is part of the lamellaphone family.

The metal tines are grouped into multiple octaves. Sounding each grouping of octaves in a left-to-right direction runs through the circle of fifths, and sounding each group in a right-to-left direction runs through the circle of fourths (unlike a piano which runs through the chromatic scale). Usually, the Array mbira contains two and a half repetitions of the entire chromatic scale, arranged in a continuous circle of fifths. The octaves of each note (A220, A440, and A880, for example) are grouped together in a staggered, nearly vertical arrangement. Each of the metal tines in a group may be played independently, and multiple octaves may be sounded together in a one-fingered stroke. The octave groups may contain as few as two octaves (two tines), or as many as five. There are 12×2.5=30 octave groups in the standard design, so a five-octave Array mbira uses 5×30=150 tines. The arrangement of the tines allows music to be played with relative ease in any key. Some models have as many as 7 Octaves so 7*30=210

Description

[edit]

Generally, the Array mbira is large enough to allow two people to play on the same instrument at once, side by side. It is a sturdy instrument, requiring only occasional care. Sounds are made by manually pushing down gently and releasing bent metal tines with a grasping fist movement of the fingers. Some contact with the finger nail helps to produce a crisp and clear tone. Low notes are played upwards with the pad of the thumb. The tines are made from high-carbon spring steel. They are individually hand-cut and ground to a smooth round shape on the ends. These tines are held down to the sounding board by two bolted crossbars. These crossbars keep the notes in tune over long periods, often many years. The names of the notes are engraved into the metal crossbar. The lower notes are closer to the player, and the higher notes are farther away. The tines are arranged so that the most consonant intervals (octaves, fifths, and fourths) vibrate along with the fundamental. Furthermore, each tine is bent at a certain angle to produce harmonics (most notably the 6th harmonic, or two octaves plus a fifth) that are more consonant than other mbiras and kalimbas.

Two types of Array mbiras are available: a hollow body and a solid body. Both models have dual piezoelectric pickups that produce two separate channels, one for the left side of the instrument and one for the right side. The hollow body is an acoustic instrument that utilizes a sound box, which can be made from a variety of domestic and exotic hardwoods. Because these instruments are handcrafted works of art, there are many options for embellishment, including various inlaid borders, burl veneers, colored lacquer and type of finish. The solid body instruments are heavier than the hollow bodies but smaller in overall size. They are better for live performances because they do not have problems with audio feedback when amplified.

Arrangement

[edit]

The notes (of which there may be up to 150,[2] comprising up to five octaves[3]) are arranged according to the Array system, developed by musicologist, performer, and author Bill Wesley.[2] The Array system of organizing the notes is similar to the Wicki-Hayden note layout, while offering the advantage of being able to play multiple octaves of the same note with one finger.

The Array system is a specific pattern of arranging musical tones. It is both isomorphic and unimorphic (meaning that harmonious notes are grouped adjacently, excluding dissonant notes). There is only one unimorphic planar (as opposed to linear) system available on a lead instrument at this time, and that is the system used for organizing the Array mbira.

Because the Array system is isomorphic, any given chord, scale, or song, no matter how complex, can be played in any one of the 12 keys immediately after the player learns to play it in one key. Because it is unimorphic, common chords tend to fall close together. In the key of C, for example, the F and G major chords can be played by moving the C major chord shape one octave group to the left or right. The same applies to Em, Am, and Dm. The minor chord shape is easier to play with the left hand, while major chords are easier to play with the right hand.

There is a row for every possible musical interval, not just fifths, fourths, and octaves but also whole tones, minor thirds, etc. The Array system can be thought of not only as being based on the circle of fifths, but as being based on rows of whole tones. Each whole-tone row is separated by a fifth/fourth.

Technique

[edit]

The experience of playing an Array mbira is that less shifting around of movement is required for playing a given chord progression. Because of the duplications of all notes available (two to three times for every octave of every note), complex rhythms and fast melodies are easier to play. The Array system allows the player to access the same notes with each hand in different locations. In addition to this, the close grouping of octaves allows large chords to be played that would require four hands on a piano. An mbira with only two or three octaves is better suited to fast, complex melodies while the larger five octave model is better suited to large chords and complex voicings.

The shorter tines sound higher in pitch. This means that any ascending scale travels away from the player toward the back of the instrument. An ascending major scale is played by playing a "three-four" pattern: do-re-mi, fa-sol-la-ti, do-re-mi, etc., going higher and higher until you run out of notes. The visual/tactile sensation of playing a group of three notes followed by a group of four notes results from the nature of the major scale: two whole steps, followed by a half step, followed by three more whole steps, and ending with one more half step to get back to "do". The minor scale and the five other musical modes work much the same way, as does the major pentatonic scale and its "modes".

One possible playing position places both hands over the notes F, C, G, D, A, E, and B, the notes of the C major and A minor scales as well as many other scales and modes. Accidentals (F#, C#, G#, D#, A#) fall immediately between and outside of the hands. This position emphasizes consonant intervals. Moving the hands further apart or closer together yields positions that emphasize dissonant intervals.

Cultural influence

[edit]

The Array mbira is played by a number of notable musicians, including Sting,[1] Ry Cooder, Emil Richards, Pharoah Sanders, Zakir Hussain, Greg Kurstin,[4] Mileece, Shannon Terry,[5] and Imogen Heap.[6][citation needed]

Array mbiras are also being used by a variety of TV and film composers. The Array mbira has been used on popular American TV shows such as Breaking Bad[7] and True Blood[8] as well as the Danish Academy Award winning film In a Better World.[9]

Its design promotes accessibility, allowing beginners to play simple melodies quickly while offering advanced players complex harmonic explorations, and it has inspired virtual instrument emulations for digital music production.

Overview

Description

The Array mbira is a handcrafted modern musical instrument belonging to the family, representing a redesign of the traditional Shona from . As a type of thumb piano, it shares roots with African lamellophones but incorporates adaptations for broader accessibility. The instrument produces a distinctive - or bell-like sound, characterized by clear, resonant tones generated by the vibration of metal tines when plucked. These tines, numbering up to 210 and spanning as many as 7 octaves, are arranged in a grid pattern based on the circle of fifths, with octaves in columns and fifths in diagonal rows, promoting ergonomic play and intuitive navigation of scales. Standard models typically feature 150 tines spanning 5 octaves. While akin to traditional African thumb pianos like the and kalimba, the Array mbira is tuned to the Western 12-tone , enabling seamless integration with instruments such as guitars and pianos across diverse musical genres. Fundamentally, it operates by plucking or pushing the tines with the thumbs and fingers to sound individual notes or chords, all housed within a portable wooden body that enhances its practicality for performance.

History

The Array mbira was invented by American and instrument designer Bill Wesley in the early , driven by the goal of modernizing the traditional African known as the to make it accessible for a wider range of Western musical styles. After about three years of experimentation, Wesley devised the core "Array System of Note Arrangement," which organizes the full across multiple s in a logical layout based on the circle of fifths, allowing intuitive playing of harmonies and melodies. This innovation addressed limitations in traditional mbiras, which typically feature limited scalic arrangements suited to specific cultural repertoires, by enabling performers to navigate all 12 tones per with ease. In 1993, Wesley partnered with skilled woodworker, musician, and composer Patrick Hadley in , , to refine and manufacture the instrument on a small scale. Hadley, with over 40 years of experience in and instrument crafting, contributed to the design and production processes, leading to the formation of Instruments as a micro-cottage industry dedicated to handcrafted builds. Initial prototypes emerged from Wesley's early work, with commercial production ramping up through this collaboration, resulting in over 300 instruments produced by the , each customized for acoustic resonance and playability. The instrument evolved from purely acoustic models to electrified variants equipped with dual piezoelectric pickups, enhancing its suitability for amplified performances in contemporary settings. Solid-body designs, which reduce feedback and improve sustain in live and recording contexts, became a key offering alongside hollow-body versions, broadening the Array mbira's applications in diverse genres. By the 2020s, production was placed on hold following the of the primary instrument tuner (as of 2025), rendering new units scarce and increasing reliance on vintage or second-hand examples among performers.

Design and Construction

Key Arrangement

The Array mbira employs an isomorphic note layout, where musical intervals maintain consistent geometric patterns across the instrument, facilitating intuitive scale and chord formation regardless of the starting pitch. This system organizes notes based on the circle of fifths in rightward diagonal rows and the circle of fourths in leftward diagonal rows, creating a grid-like structure that repeats predictably through octaves. For instance, the diatonic sequence "DO RE MI FA SO LA TI" appears in uniform blocks for any , enabling musicians to visualize and play harmonies without reorienting to new positions. The design is also unimorphic, featuring uniform spacing between notes that eliminates fixed ; players can use either hand interchangeably for any note without relearning patterns, promoting ergonomic accessibility for both left- and right-handed individuals. Structurally, the tines are arranged in concentric circles or arcs on a large soundboard, typically spanning five octaves with up to 150 metal tines tuned chromatically from low C to a high B. This configuration can extend to seven octaves in grand models, positioning key intervals such as major thirds and perfect fifths in close proximity to minimize awkward reaches. These features offer significant advantages for playability, including seamless key changes without retuning, as the isomorphic grid supports transposition by simply shifting hand position. The layout enhances polyphonic capabilities by surrounding each note with harmonious intervals—such as octaves, fifths, and thirds—allowing simultaneous , , and bass lines with minimal disruption. Compared to linear kalimbas, the circular arrangement reduces finger travel by up to half in some patterns, streamlining complex progressions. In contrast to traditional mbiras, which typically adhere to heptatonic scales with resonators and culturally specific tunings, the Array mbira adopts a full chromatic Western tuning for broader versatility across musical genres. This shift enables precise intonation and integration with other instruments, while preserving the thumb-plucked tine resonance in a more expansive, piano-like framework.

Materials and Build

The Array mbira features tines crafted from , individually tuned by adjusting their lengths to produce varying pitches, with longer tines yielding lower notes. These tines are secured to an anchor board using a bolted assembly with crossbars, providing stability for tuning and facilitating straightforward replacement or adjustment, distinguishing it from traditional mbiras that often rely on wedging or gluing. The instrument's body was handcrafted in , , using sustainably sourced hardwoods such as , African shedua, or exotic options like macassar ebony and , selected for their and . As of 2025, production is on hold due to the retirement of the instrument tuner. Two primary body types are available: the acoustic hollow body, which serves as a box for natural sound amplification, and the semi-hollow body, a more compact hybrid design that reduces feedback while supporting electric amplification. All models incorporate dual piezoelectric pickups positioned under the compression bar for stereo output, capturing the full range of tine vibrations accurately. Assembly involves precise woodworking to integrate the bolted tine system with the body, followed by tuning to standard concert pitch (A=440 Hz) for compatibility with Western music. For example, a 5-octave acoustic model measures approximately 20 × 30.5 × 5.5 inches and weighs 23 pounds, emphasizing its robust, professional build. Maintenance typically requires periodic re-tensioning of the tines to preserve intonation, especially in varying humidity conditions.

Playing and Performance

Technique

The Array mbira is typically played while held horizontally on the player's lap for smaller models or placed on a stand angled for optimal access to the tines, allowing the performer to sit comfortably during extended sessions. Sound is produced by plucking the curved metal tines with the and forefingers, pushing them toward the body to initiate , a technique derived from traditional playing but adapted to the instrument's chromatic layout. Basic finger techniques involve alternating thumbs to execute melodies across the circle-of-fifths arrangement, while the index and middle fingers handle bass notes and chords on the lower tines, enabling fluid movement between single notes and multi-note harmonies. is controlled by pressing the palms against the tines or soundboard to mute unwanted resonance, providing precise sustain management essential for rhythmic clarity. The layout facilitates forming large chords of multiple notes simultaneously, supporting musical applications such as improvising common progressions like I-IV-V in any key through simple left-to-right plucking patterns, without the need for complex hand repositioning. Rhythmic patterns draw inspiration from traditional African styles but are readily adapted for contemporary genres including and rock, thanks to the instrument's compatibility with the Western 12-tone scale and its ability to integrate , , bass, and in one . Advanced players can enhance the sound by integrating the Array mbira with amplification systems and effects pedals, allowing for processed tones while preserving the instrument's natural harp-like . The intuitive array arrangement makes the learning curve gentler than that of traditional mbiras, as it simplifies access to all chromatic notes and chord voicings, rendering it accessible for musicians of varying skill levels.

Models and Variants

The Array mbira is available in standard models spanning 3, 4, or 5 s, with the 3-octave version (ranging from C2 to B4) serving as a portable option suitable for beginners due to its compact size. The 4-octave model (C2 to B5) offers an intermediate range, while the 5-octave classic (C1 to B5) provides versatility for a wide array of musical applications, featuring 150 tines arranged in 30 octave groups. Custom extended ranges, such as up to 7 octaves with 210 tines, are possible for professional users seeking grand-scale performance capabilities. Body variants include the acoustic hollow design, which enhances resonance through a larger soundbox and produces a rich, guitar-like volume unplugged. The semi-hollow body combines elements of the acoustic model with increased portability and louder projection, incorporating a built-in 2-channel piezoelectric pickup system for amplification across all variants. The solid-body electric variant, once offered for compact stage use with integrated preamp, has been discontinued. Custom options allow for modifications such as alternative hardwoods like or other domestic and imported species to achieve brighter or varied tones, while ensuring no endangered materials are used. Additional customizations include micro-tonal tunings by instrument designer Bill Wesley and adjusted note ranges, though the unimorphic layout reduces the need for left-handed . Virtual emulations replicate the instrument digitally, with the Soniccouture Kontakt modeling a 5-octave acoustic version complete with 2-channel pickup simulation for recording and performance. As of , production by Instruments is on hold following the retirement of the primary instrument tuner, leaving the second-hand market as the primary source for physical instruments until a new tuner is hired.
